Abstract

The periodontopathic bacterium Actinobacillus actinomycetemcomitans possesses a 35-kDa periplasmic iron-repressible protein. Its regulation is mediated by the Fur protein, as was inferred from the Fur-binding consensus sequence at the -35 position of the gene for the 35-kDa protein and from the relaxed expression of the gene in a mutant with an altered Fur-binding sequence. The 35-kDa protein, designated AfuA, has strong homology to HitA and FbpA of Haemophilus influenzae and Neisseria meningitidis, respectively, which serve as periplasmic iron transport proteins.
